A section of this dna molecule that codes for a specific inherited trait is called GENES. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
I think it is either y or z. It has been a little bit since I have done this unit though...
C.
The nonnative species would not affect biodiversity because it's unlikely the species would survive.
Answer:
<em>Escherichia coli </em>- Facultative anaerobe
<em>Micrococcus luteus </em>- Obligate aerobe
<em>Clostridium sporogenes</em> - Obligate anaerobe
Explanation:
In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are <em>Mycobacterium tuberculosis </em>and <em>Micrococcus luteus</em>.
Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the <em>Escherichia coli</em><em>.</em>
Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are <em>Clostridium sporogenes</em><em> </em>and <em>Clostridium botulinum.</em>
